Colour cluster analysis for pigment identification [PDF]

open access: yesSPIE Proceedings, 2008
This paper presents image processing algorithms designed to analyse the colour CIE Lab histogram of high resolution images of paintings. Three algorithms are illustrated which attempt to identify colour clusters, cluster shapes due to shading and finally to identify pigments.

Pigments and Mixtures Identification by Visible Reflectance Spectroscopy [PDF]

open access: yes, 2013
Non-invasive techniques, as well assessed, are commonly used as preliminary investigations on the superficial constitutive materials of works of art.In particular, when the sampling on the artwork is not permitted, non-invasive techniques, such as ...

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

open access: yesMolecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

The major carotenoid pigments of the grain aphid, Sitobion avenae (F.) (Hemiptera: Aphididae) [PDF]

open access: yes, 1999
The economically important grain aphid, Sitobion avenae (F.) shows colour polymorphism with brown and green forms predominating. Colour is determined both genetically and in response to environmental factors, including nutrition.

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

open access: yesFEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...
